Is there any differences between batched 0 and batched xx?

Hi guys

A lot objects in my game are sharing the same material. Here is what I see in the stats:

Draw calls: 6. Batched: 20.

Is there any performance differences between that stat and Draw calls: 6. Batched: 0?

The game is for mobile. Is it worth the time to tweak it to Bachted: 0.

Thanks!
